Results: The meanvalue of mean inorganic phosphate in non stone formers were less than that of stone formers. The mean of urinary inorganic phosphateexcretion in stone formers was greater than that of non-stone formers. Conclusions: We conclude that inorganic phosphate is an independentrisk factor for renal stone formation.
